Application filed'September 1 0, 1920. Serial No. 409,507.-

To all whom it may concerm I Be it knownthat we, ELISHA F. PARKS, Jr,

and PHILIP G; LANG, Jr., citizens of the United States, residing, respectively, at. Timonium, Baltimore County,'in the State of Maryland, and Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Trimmer-Belt Attachments; and we do hereby declare the following to be a full, clear, and exact description of the inventiomsuchas will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to attachments for trimmer belts, such as are used in storing cargoes of coal or other materials on board ships, or in placing said materials in bins or other storage receptacles.

Among the objects of our invention are:

To produce an attachment which can be readily secured to any approved form of belt.

To produce an attachment which can be blanked andshaped readily by means of diesv so that the samecan be furnished at a reasonable cost.

Heretofore, attachments have been secured to trimmer belts in a variety of ways, but the mode of attachment was usually complicated or required a packing of leather under the attachment.

By the use of ourimproved attachment, the use of complicated securing devices and leather packing is entirely avoided.

In carrying out our'invention we make use of the instrumentalities illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a portion of trimmer belt showing two forms ofour improved attachment secured thereupon.

Fig. 2 is aside elevation of said belt and attachment. 7 v

Fig. 3 is a view of either form of our improved trimmer attachment viewed in the direction of the arrow 3 in Fig. 2 but with the teeth 10 not bent over. 1

In the drawings:

5 is a belt which may be of leather or any approved woven fabric, of any suitable width, driven inany approved manner and controlled by any suitable mechanism so that the faces of the attachments will be directed against the bulk material that is to .be trimmed.

The attachments shown at consist of a fiat top? having ends 88 bent at right angles thereto, said ends terminating in the approximately straight edges 99 from which project the teeth 10. The teeth 10 may be of any approved contour.

In applying our improved attachments to the belt 5 the teeth 10 are driven through the body of the beltand then bentover as shown in Fig. 2 so as to secure said attachments to It is to be noted that when the teethlO are the belt.

driven through the belt 5, as just described,

the edge 9 presses against the adjacent side of said belt and thus the top 7 is secured at the proper distance. from thesurface of said belt.

It is evident that the ends 8 may be ofany suitable length so that the top 7 will stand at any suitable distance from the belt 5. Y v 1 I The attachment shown at 11 is substanthe surface of tially the same as the attachment shown at 6 excepting that the top 12 is made sinuous so that the under surface thereof will contact with the adjacent surface of the belt 5 substantially midway between the ends 13- 13 for the purpose of giving additional rigidity to said top.

It is evident that with this structure the ends 13-43 may be placed any distance apart and there may be as many contacts as are desired between said ends of the under surof the belt 5. v

vThe attachment. shown at 11 is otherwise faceof the top 12 with the abutting surfaces the same as the attachment shown at 6 and v r is secured tothe belt 5 in a similar manner. In Figure 1 we have shown three of each type of our improved attachment secured in mutual alignment, but it is to be understood that we may use any number in alignment, or

that we may use them staggered, or that we may make them of any width sovthat they cover practically the full width of the belt,

if desired.

Thus,- we produce a simple, cheap and efiicient attachment with trimmer belts, which can be secured in place at a minimum cost.

We claim v r 1. A trimmer belt attachment comprising a sinuous top, bent ends each havingfteeth 1 thereon and straight edges between said teeth, said straight edges being in substantially the same plane as the lower surface of said top. belt and bent against the other side thereof.
